Symptom is that ZMQ_STREAM sockets in 4.1.0 and 4.1.1 generate zero sized messages on each new connection, unlike 4.0.x which did not do this. Person who made this commit also changed test cases so that contract breakage did not show. Same person was later banned for persistently poor form in CZMQ contributions. Solution: enable connect notifications on ZMQ_STREAM sockets using a new ZMQ_STREAM_NOTIFY setting. By default, socket does not deliver notifications, and behaves as in 4.0.x. Fixes #1316
ZeroMQ
Welcome
The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.
